I've been looking everywhere for a package tracking app that both syncs with Amazon, and pulls tracking numbers out of email. Slice (slice.com) used to do it, but their amazon sync broke. Shop.app will pull the tracking info out of emails, but doesn't sync with Amazon (so you just get item counts, not item names). Deliveries seems like the best UI, and has amazon sync, but needing to manually add all my non-amazon/ebay purchases is such a bummer.
